The physical nature of light is an intriguing scientific mystery as it behaves like a wave in free space and as a particle ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the ...

The work is deductive in plan; its foundations are the electromagnetic equations of Maxwell and Hertz, together with the Larmor-Lorentz expression for the mechanical, force on a moving charge.

IN spite of the great progress made in recent years, the theory of radiation is still in rather an unsatisfactory state. By the methods of Schrödinger it is possible to express the radiation of ...

An international group of physicists has traced the origin of an electromagnetic interaction to the Dirac equation, a fundamental equation of quantum physics. The interaction couples the spin of the ...

Many physical phenomena – including heat transfer, fluid flow and electromagnetic wave propagation, to name just three – can be described using partial differential equations (PDEs). Apart from a few ...

Electromagnetic radiation is just waves of moving energy, but when we tune into radio or TV stations, we don't talk about their energy — it's all about frequency.

They pointed out that electromagnetic waves encode mathematical functions in their amplitudes and phases – both of which can be transformed by metamaterials. This led the team to suggest that ...
